It's one of the few things I would change. My job was obsolescent almost before I finished training for it. Given a second bite of the cherry I'd probably get a degree in commerce.
The bible study I enjoyed was about Hebrews 6:12," Be imitators of those who through faith and patience inherit the promise" I learned about men and women who had faith in God and who's lives turn out for the good because of listening and obeying God.
